Pictures: Earth Hour 2019 in Tórshavn

Cities around the world were marking Earth Hour on Saturday by turning off lights at 8:30pm local time in a call for global action on climate change.

The Earth Hour gesture calls for greater awareness and more sparing use of resources, especially fossil fuels that produce carbon gases and lead to global warming. Beginning in Sydney in 2007, Earth Hour has spread to more than 180 countries, with tens of millions of people joining in.
